See Carrie Underwood in New Athleisure Campaign After Accident: 'She Looks Gorgeous in Person'

In a behind-the-scenes photo from her fall and winter campaign shoot for CALIA by Carrie Underwood, the country superstar works out with a kettlebell as she rocks the latest looks from her line.

“I’m so proud of this collection,” 35-year-old Underwood — who’s now recovered from a scary fall last November outside her Nashville home — tells PEOPLE exclusively.

For all the details on Underwood’s recovery and her big return to the stage, pick up the latest issue of PEOPLE, on newsstands Friday.

Last week, the American Idol winner opened up for the first time on iHeartRadio’s The Bobby Bones Show about her frightening fall, explaining that it happened when she went to take her dogs out for a quick walk at night.

“I was taking the dogs out to go pee one last time, and I just — I tripped,” she said. “There was one step, and I didn’t let go of the leashes! Priorities! So that’s why my left hand’s fine. But I went to catch myself and I just missed a step.”

“If I had fallen anywhere else, I would have been perfectly fine. But it was one step that messed everything up,” she added.
